Default Parameters for EMCPvMeCtlEPtStTest

An Expander Port refers to the connection slot(s) used to connect the storage system or unit to multiple storage systems or units. Since the expander ports play a crucial role in expanding the storage capacity of a storage solution, error-prone ports, disconnected ports, or faulty/degraded ports, can deny remote hosts access to the additional storage capacity that has been made available via these ports. To prevent this, administrators will have to rapidly detect port-related abnormalities and swiftly initiate measures to correct them, so that the expanded ports, and through them the attached storage systems, are always accessible. To capture these abnormalities and instantly bring them to the attention of administrators, use the EMCPvMeCtlEPtStTest. For every expanded port in the storage system, this test reports the current status and overall health of the port, and thus leads administrators to defective ports.

This page depicts the default parameters that need to be configured for the EMCPvMeCtlEPtStTest.

• The TEST PERIOD list box helps the user to decide how often this test needs to be executed.

• By default, this test always connects to the Host to collect metrics. If the Host is unavailable, then the test will not be able to execute. This is because, the Additional Controller IP is set to none by default.

  If the monitored storage device has two controllers, then you can configure the test to connect to an alternate controller, if the host is unreachable. For this purpose, specify the IP address of the alternate controller in the Additional Controller IP text box.

• In order to monitor a EMC PowerVault ME storage system, the eG agent has to be configured with the credentials of a user who has been assigned the Monitor role. Specify the login credentials of such a user in the USER and PASSWORD text boxes. To know how to create such a user, refer to Pre-requisites-for-monitoring-the-EMC PowerVault-ME-storage-system. Confirm the password by retyping it in CONFIRM PASSWORD text box.

• The Management Controller of the EMC PowerVault ME storage system provides access for monitoring and management via the HTTP and HTTPS protocols for XML API request/response semantics. To enable the eG agent to access the management controller, invoke the XML API commands, and collect the required metrics, you need to specify the SERVICE PORT on the controller that listens for HTTP/HTTPS requests for XML API semantics. By default, this is port 80.

• Specify the time duration for which this test should wait for a response from the storage system in the TIMEOUT text box. By default, this is 60 seconds.

• By default, EMC PowerVault ME system is not SSL-enabled. This is why, SSL flag is set to False by default. If it is SSL-enabled, then change this flag to True.

• Once the necessary values have been provided, clicking on the UPDATE button will register the changes made.

When changing default configurations of tests, the values with “$” indicate variables that will be replaced by the eG system according to the specific server being managed - for instance, $hostName is the host/nickname of the target host, $port is the port number of the server being monitored. E.g., for a server xyz:80, $hostName will be changed automatically by the eG manager to “xyz*” and $port will be changed to “80” when configuring a test.
